CHURBA!!!
Yeah, I live. Things have just been rough lately, so I've been somewhat incommunicado. Sorry man.
Nope. Speed tests, ping tests all fine. Besides if that were the problem the main page wouldn't have loaded.
The two machines were on entirely different networks across the city from each other. Which is different than AT&T's network.
Problem resolved later in the morning.
Not quite what I meant - I meant a problem not with the way the ISP is serving you data, but a problem with the ISP and whatever server is serving the data to them - another example is that sometimes Icanhascheeseburger's image server will have problems with british ISPs, and if you're in any way using that ISP, you cannot view the images at all, even though everything else you use online works fine. The problem correcting itself might be a sign this was the case, but doesn't explain why it was the case across both/all three networks you tried.
Sorry I didn't explain myself better, I'm savvy, but I'm not exactly an IT guy.
